摘要: A tape measure 20 includes a display window 24 for presenting a digital presentation of the measurement being made. The tape measure 20 includes an encoder 74 which provides for a combined absolute scale 95 and relative scale 105 for determining the measurement. Perforations 62 in the tape 26 are mated with pins 60 extending from a capstan 58 in order to cause the encoder 74 to send signals to a microprocessor 76. The microprocessor 76 processes the signal and displays the measurement.
